Lane bin due for replacement? True, definitely (10)
I believe the answer is:
undeniable
'true definitely' is the definition.
'undeniable' can be an answer for 'true' (thesaurus). I am unsure of the 'definitely' bit.
'lane bin due for replacement?' is the wordplay.
'for replacement?' indicates an anagram (I've seen this in other clues).
'lane'+'bin'+'due'='lanebindue'
'lanebindue' with letters rearranged gives 'UNDENIABLE'.
Can you help me to learn more?
(Another definition for undeniable that I've seen is " Indisputable".)
